Android downloads have grown from 1 billion total in July 2010 to 10 billion seventeen months later.

"One billion is a pretty big number by any measurement," Eric Chu, director of the Android Ecosystem, said in a blog post. "However, when it's describing the speed at which something is growing, it's simply amazing. This past weekend, thanks to Android users around the world, Android Market exceeded 10 billion app downloads—with a growth rate of one billion app downloads per month. We can't wait to see where this accelerating growth takes us in 2012."
